Improvement in shingle-machines



UNrrED STATES OLIVER A. OLMSTED, OF SEBASTOPOL, CALIFORNIA.

IMPROVEMENT IN SHlNGLE-NIACHINES.

Specication forming part of Letters Patent No. 116,988, dated July l1, 1871.

To all whom it 'may concern:

Be it known that I, OLrvnn A. OLMsTnD, of Sebastopol, in the county of Sonoma and State of California, have invented a new and useful Improvement in Shingle-Machines, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to a new and useful improvement in machines for manufacturing shingles; and consists in the construction and arrangement of parts hereinafter described.

In the accompanying drawing, Figure I represents a vertical longitudinal section of the machine taken on the line .r of Fig. 2. Fig. 2 is a top or plan view.

Similar letters of reference indicate corresponding parts.

. A is the frame which supports the operating parts of the machine.` B is the driving-shaft, to the outer end of which the power is applied. On the inner end of this shaft there is a driving cog-wheel, C'. D is a'cogwheel on the shaft E, which shaft is placed parallel with the shaft B. The cog-wheels C and l) mesh into each other. The latter wheel, I), is a crank-wheel, by which the carriage which bears the splitting-knife and guides the 'shaving-knives is operated. E is the carriage.' F is the splitting-knife. Gis the bed. The block or bolt from which the shingle is to be cut is placed in the recess H. The revolution of the wheel I) carries the carriage by means o'f the pitman I, which is connected with the wheel at J As the knife F is forced forward it splits a shingle from the bolt, which shingle is guided by the spring k onto the lower stationary bed L. As the carriage E returns, the butt end of the shingle is forced between the stationary shaving-knives on n, which are attached to and supported by the rods o o on each of the ends of the knives. `As the carriage is drawn back for shaving the shingle, the knives m and n are gradually forced toward each other by the carriage, which gives the taper to the shingle. The shingle, when shaved in this manner, drops down with the shaving from the upper side, while the under shaving is conducted down by the curved plate P. In being shaved the shingle passes over the roller It, by which it is carried back after it leaves the knives. The bolt is held down by the dog S, which is raised by means of a treadle, and supported in an upright position by the arms T T. U is a knife for jointing the shingle in the bolt. This knife works vertically in an upright frame in guides V V. The knifeframe is connected by the pitinan WV with the pulley zr, as seen in Fig. l. The pulley .r is revolved, by means of the belt y, from a pulley on the drivin g-shaft B. It will thus bel seen that a shingle is split from a bolt and shaved at each revolution ofthe driving-wheel. The shavingknives are made adjustable by set-screws, so that they will shave the sides of the shingle evenly.

I do not confine myself strictly to the manner of construction shown as regards the articles. I am aware that the details may be varied without varying the main or principal features of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In the shingle-machi1'1e,the arrangement of the dog` S, jointing-knife U, and splitting and shaving devices, snbstantiallyas shown and described. l

2. The carriage E, with the spring K attached to the pitinan, and operating substantially as and for the purposes described.

The above specification of my invention signed by me this 21st day of February, 1871.

OLIVER A. OLMSTED.
